    Phytomining ScienceDirect

    Phytomining is the production of a `crop' of a metal by growing high-biomass plants that accumulate high metal concentrations. Some of these plants are natural hyperaccumulators, and in others the property can be induced. Pioneering experiments in this field might lead to a `green' alternative to existing, environmentally destructive, opencast mining practices. Phytomining for a range of

    Phytomining is a ‘green’ technology that should appeal to the conservation movement as an alternative to opencast mining of low-grade ores. Currently, phytomining has only limited potential application (see our 2015 article below). However, he economic viability of phytomining improves as the price of metals increases. With China’s booming economy, metal prices are set to increase

    Phytomining and Bioleaching GCSE Triple Award Revision

    Phytomining and Bioleaching. Metal ores are a finite resource which are in limited supply. New methods of copper extraction exploit waste ores and low grade ores. Phytomining involves growing plants on top of low grade ores. The plants absorb copper ions through their roots The plants are then burnt to ashes containing copper ions. These ions are leached from the ash using sulfuric acid. Scrap

    GCSE CHEMISTRY Extraction of Copper Thermal

    Phytomining. Some plants absorb metal compounds (including copper) when they grow. The plants can then be burned and the metal is extracted from the ash. The process is called phytomining and it can also be used to extract metals from contaminated land. Brassicas (the cabbage family) can extract metals including cadmium, cobalt and nickel. Copper can also be extracted by displacement from a

    Evaluate the Use of Phytomining and Bioleaching in Metal

    However, phytomining is a slow process, and produces fairly small amounts of metal compared with conventional techniques. Another way of using phytomining is to remove toxic metals from contaminated ground. If we grow hyperaccumulators on contaminated ground, they will remove the toxic substances from the soil, making it safe to use again. Bioleaching uses bacteria, rather than plants, to
